Mine does not sounds so bad like the youtube clip but it is that sound, the timing belt was last time done in 2014, i think it was without the tensioner.
The car is not stock, the jets are replaced, i think it has something arround 300-350 hp, my end goal isrround 450-500 hp, i has Greddy exhaust, Haltech Elite 2500 Ecu, De Cat test pipes, i will do a turbo kit upgrade next year i think, with arround 800cc injectors, new turbo kist and so on,
I can't find anything about the Oil pumps, if it is a bad pump
